This article describes modelling and simulation of heating and calcination of raw meal particles. The purpose is to determine the time required to obtain a certain calcination degree for particles that are exposed to surroundings with a specified temperature. The impact of applying different reactor temperature values and different particle sizes is investigated. The aggregated calcination degree as a function of time is calculated for a typical raw meal with a specified particle size distribution and with different contents of CaCO3 in different size classes. The developed model can be used as a basis for determining the required size of potential new calciner reactor types.
